https://learn.jquery.com/ is a maintained online resource. At the bottom it also links to three books (the third seems to be a free PDF version). Personally I learned it via a book and use http://jqapi.com/ now to check for syntax.
Don't use jQuery. Just learn plain JavaScript. People seem to enjoy the book Eloquent JavaScript.
Then learn a common frontend library like React. People also seem to love Vue.
Pick some UI Kit and framework (nowadays Bootstrap is the only answer).
There are lots of tutorials and open source projects on GitHub
